Craig Rogers’s review published on Letterboxd:
I was (am) the lead restoration artist on the new 4K restoration that'll be rolling out a bit later this year (2015). I must say while I worked on it, the visuals had me scratching my head. It runs the gambit from gorgeous watercolor paintings one moment to crude drawings of some truly weird shit the next. I honestly didn't know what to expect when I finally was able to watch it as a whole...and my hopes and expectations were quite low.
Then I saw it. Wow. I can honestly say I've never seen anything quite like it and it's so much more than the sum of it's parts. The artwork is amazing. The voice actors (particularly Tatsuya Nakadai as the devil!).
Be warned though - there are scenes of rape. It also features pretty much every kink you can imagine.
